我一直在研究几乎完全相同的事情......我取得了一些进展。将此添加到代码的顶部。（基本上这是什么东西做的是捕捉您收到当您第一次访问该页面一个cookie，你的代码将在以后重新使用它，您无需进行任何进一步的修改）

一些东西......

将您的cookie容器声明移动到最顶端。
我可能需要在两行中都更改“http://www.amazon.com”。
将UserAgent更改为您所需的。
这仍然不工作......因为...... 亚马逊的referrer链接和appActionToken链接不断变化。

一旦我们克服了这个问题，我们应该能够得到这个工作，如果它可能以某种方式实时捕获这些链接。我在考虑webrequest可能会有所帮助，然后链接可能会在发布后立即更改。

我得到了这个工作的另一个网站，给出一个非http：//链接，如appActionToken是，但他们的链接是静态的，不会改变。我能够使用他们的域名（即：http：\ www.website.com），我在那里放置了http：\ www.amazon.com。尽管此链接可能需要更改为其登录页面。

如果您有任何进一步的进展，我很乐意听到它！

Dim tempcookie As New CookieContainer 
 

 
     Dim postreq1 As HttpWebRequest = DirectCast(WebRequest.Create("http://www.amazon.com"), HttpWebRequest) 
 
     Dim postresponse1 As HttpWebResponse 
 
     postresponse1 = DirectCast(postreq1.GetResponse(), HttpWebResponse) 
 
     postreq1 = DirectCast(HttpWebRequest.Create("http://www.amazon.com"), HttpWebRequest) 
 
     postreq1.UserAgent = "mozilla/5.0 (windows nt 5.1) applewebkit/537.36 (khtml, like gecko) chrome/40.0.2214.111 safari/537.36" 
 
     postreq1.Timeout = 60000 
 
     postreq1.CookieContainer = tempcookie 
 
     postreq1.Method = "get" 
 
     postreq1.AllowAutoRedirect = True 
 
     postreq1.ContentType = "application/x-www-form-urlencoded" 
 

 
     postresponse1 = DirectCast(postreq1.GetResponse(), HttpWebResponse) 
 

 

 

 
     Dim datastream As Stream = postresponse1.GetResponseStream() 
 
     Dim reader As New StreamReader(datastream) 
 
     Dim responsefromserver As String = reader.ReadToEnd()

也底部3线可以是或可以不是必需的。

这是我的其他代码以防万一。

Dim postdata As String = "appActionTokenXXXXXXXXXXXXXXX THIS CHANGES" 
 
     'Dim tempcookie As New CookieContainer 
 
     Dim encoding As New UTF8Encoding 
 
     Dim bytesdata As Byte() = encoding.GetBytes(postdata) 
 
     Dim postreq As HttpWebRequest = DirectCast(WebRequest.Create("https://www.amazon.com/XXXXX - THESE CHANGE"), HttpWebRequest) 
 

 
     postreq.Method = "POST" 
 
     postreq.KeepAlive = True 
 
     postreq.CookieContainer = tempcookie 
 
     postreq.ContentType = "application/x-www-form-urlencoded" 
 
     postreq.Referer = "https://www.amazon.com/XXXXX - THESE CHANGE" 
 

 
     postreq.UserAgent = "Mozilla/5.0 (Windows NT 5.1) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/40.0.2214.111 Safari/537.36" 
 
     postreq.ContentLength = bytesdata.Length 
 

 
     Dim postreqstream As Stream = postreq.GetRequestStream() 
 
     postreqstream.Write(bytesdata, 0, bytesdata.Length) 
 
     postreqstream.Close() 
 
     Dim postresponse As HttpWebResponse 
 
     postresponse = DirectCast(postreq.GetResponse(), HttpWebResponse) 
 
     tempcookie.Add(postresponse.Cookies) 
 
     logincookie = tempcookie 
 
     Dim postreqreader As New StreamReader(postresponse.GetResponseStream())
